Advanced polymer modifier could boost its take up in packaging - DuPont Packaging

February 23/2011

(Food Production Daily) --
An advanced polymer modifier that tackles a host of limitations linked with
polylactic acid (PLA) could boost its take up in packaging, said DuPont
Packaging & Industrial Polymers.

Latest trials by the US-based company have shown its Biomax Strong 120
delivers “remarkable toughening effects” in brittle PLA materials, cuts power
consumption and increases thermal stability during extrusion, according to Dr
Carol Casarino, packaging and consumer global technology manager.

The modifier can also have a dramatic effect in reducing crinkly film
noise – which has so far restricted its acceptance in flexible packaging
application such as snack bags, said DuPont.

The firm said recent testing had revealed the new benefits from this PLA
modifier that “could speed the growth of PLA polymers in packaging”.
